Abstract (en)
[origin: WO9002968A1] Adverse environmental effects may be canceled from an optical processor which adjusts the phase of spatially distributed frequency components. This is achieved by projecting the optical modulated signal and a local oscillator optical signal along the same optical path and through the same optical components (9, 18', 20', 26, 30). Multichannel operation is achieved by positioning the optical components for each stage along a common axis.
